Question

A load of bricks with mass m1 = 15.0kg hangs from one end of a rope
that passes over a small, frictionless pulley. A counterweight of
mass m2 = 28.4kg is suspended from the other end of the rope, as
shown in the figure. The system is released from rest. Use g =
9.80m/s^2 for the magnitude of the acceleration due to gravity.
(A)What is the magnitude of the upward acceleration of the load of
bricks?(B) What is the tension in the rope while the load is
moving?
